Connecting the Controller to a Network
Connect the controller to an Ethernet network using Ethernet port 1 on
the controller front panel. Use a standard Category 5 (CAT-5) or better
Ethernet cable to connect the controller to an Ethernet hub or a computer.
Caution To prevent data loss and to maintain the integrity of your Ethernet installation,
do not use a cable longer than 100 m. If you are using 100 Mbps Ethernet, National
Instruments recommends using a CAT-5 or better shielded twisted-pair Ethernet cable.
If you need to build your own cable, refer to the Cabling section for more
information about Ethernet cable wiring connections.
Note You will configure the IP settings and install software on the controller, as described
in the Configuring IP Settings and Installing Software on the Controller section, after
connecting power and powering the controller on.
The host computer communicates with the controller over a standard
Ethernet connection. If neither the host computer nor the CompactRIO
controller is connected to a network, you can connect the two directly.
Note You must connect Ethernet port 1 to configure the cRIO-9025. You cannot configure
the controller through Ethernet port 2.
In order to use Ethernet port 2, you must assign a static IP address to the
port using MAX. The IP address must be on a different subnet than the
IP address of Ethernet port 1. You cannot use DHCP with Ethernet port 2.
For more information about using Ethernet port 2, go to ni.com/info and
enter the info code dualenet.

Wiring Power to the Controller
Caution You must install the controller on a CompactRIO chassis, or on a stand-alone
mounting kit such as the NI 9908 or NI 9909, and tighten the captive screws before you
apply power to the controller. Installing the controller while power is applied to it can cause
damage to the chassis.
The controller requires an external power supply that meets the
specifications in the Power Requirements section. The controller filters and
regulates the supplied power and provides power for all of the I/O modules
in the chassis. You must connect a power supply to at least one pair of
V and C terminals. Optionally, you can connect a power supply to the
other pair of V and C terminals. The controller draws power from the
power supply with the higher voltage. The controller has one layer of
reverse-voltage protection. Complete the following steps to connect a
power supply to the controller.
1. Install the ferrite shipped with the controller across the negative and
positive leads of the power supply, approximately 50–75 mm (2–3 in.)
from the ends of the leads near the controller. Refer to the following
figure for an illustration of this step.
Figure 4. Installing the Ferrite
2. Connect the positive lead of the power supply to the V1 or V2 terminal
and the negative lead to one of the C terminals.
3. Optionally, you can connect the positive lead of another power supply
to the other V terminal and the negative lead to one of the C terminals.
You must install the ferrite across both pairs of wires.
Note If you connect power to both V1 and V2, you must ensure that the voltage difference
between the two power inputs, measured at the controller power connector, is at least
500 mV.
Note The controller draws power from either V1 or V2 depending on which terminal has
a higher voltage. It does not draw power from both terminals. The controller switches
between V1 and V2 without affecting operation.

cRIO-9025 Operating Instructions and Specifications 6 ni.com
Caution The C terminals are internally connected to each other. If you use two power
supplies, make sure that they share a common ground.
Caution The C terminals are internally connected to the controller chassis to prevent a
faulty ground connection from causing the chassis ground to float. If you reverse the input
voltage, the positive input voltage is connected directly to the chassis. The controller
has built-in reversed-voltage protection, but reversed voltage can damage connected
peripherals if the chassis ground is not reliably connected to earth ground.
Caution Do not tighten or loosen the terminal screws on the power connector while the
power connector is plugged into the controller or while the power supply is on.
Powering On the Controller
Turn on each power supply to the CompactRIO system. The controller runs
a power-on self test (POST). During the POST, the Power and Status LEDs
turn on. When the Status LED turns off, the POST is complete. If the LEDs
do not behave in this way when the controller powers on, refer to the
Understanding LED Indications section.
Configuring IP Settings and Installing Software
on the Controller
When you power on the controller for the first time, it boots into safe mode
because there is no software installed on it. This section describes how to
configure the IP settings and install software on the controller.
Complete the following steps.
1. Launch MAX on the host computer and expand Remote Systems in
the MAX configuration tree. MAX lists the cRIO controller as the
model name of the controller followed by the serial number, for
example, NI-cRIO9025-00108562.
Tip If the controller is on a different subnet from the host computer, it does not appear
under Remote Systems the first time you power it on. You can use the CONSOLE OUT
switch to read the IP address of the controller, and add it to Remote Systems in MAX. Refer
to the CONSOLE OUT Switch section for information about using a serial connection and
a terminal program for network configuration and troubleshooting.
The controller automatically attempts to connect to the network using
DHCP. If DHCP is not available, the controller connects to the network
with a link-local IP address with the form 169.254.x.x.
2. Select the controller under Remote Systems to see the Network
Settings tab in the middle pane of MAX.
